Umm, I guess I'm not sure why you'd need to bridge the insulator with a
resistor but everything else sounds fine. Typical clevis (shackle) sizes are
twice the diameter of the wire; i.e. for 1/4" guy wire, use 1/2" clevises. If
in
doubt, over-engineer it. BTW those bent bolt clevises are designed for
insulator attachment.
The only caution with PLP Preformed grips is that there are 2 crossover
marks on them; the first one closest to the end loop is for normal thimble
connections. The second set is for use when they go thru insulators; the grip
angle is shallower and it puts less strain on the grip strands. Other than
that,
you should be good to go.
